MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 541,948, dated July 2,1 895. Application filed June 14, 1894. Serial No. 514,561 (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM G. PRICE, a citizen of the United States,residing at Frackville, in the county of Schuylkill and State ofPennsylvania, have invented a new and useful Miners Lamp, of which thefollowing is a specification.

The invention relates to improvements in miners lamps.

The object of the present invention is to improve the construction ofminers lamps, and to provide a simple and inexpensive one, which willreadily maintain itself in a per pendicular position, which will preventthe flame from coming in contact with a miners face, and in which thebody of the lamp will be protected from the flame.

A further object of the invention is to enable animal or hydro-carbonoils to be successfully burned.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a miners lampconstructed in accordance with this invention. Fig. 2 is a centralvertical sectional view of the same. Fig. 3 is a detail perspective viewof the detachable shield. Fig. 4 is an elevation of a miners lamp,illustrating a modification of the invention, and showing a constructiondesigned for burning hydro-carbon oils. Fig. 5 is a central verticalsectional view of the same. Fig. 6 is a detail sectional view,illustrating the manner of securing the shield by bands.

Like numerals of reference indicate corresponding parts in all thefigures of the drawlugs.

1 designates a rectangular lamp body provided at its inner or rear sidewith a hook 2 and having at its front a wick tube 3. The hook isconstructed of wire, or other suitable material, and its shank 4 isextended through a perforation 5 of the back of the body of the lamp andsoldered, or similarly secured, within the lamp body to the inner faceof the back thereof, thereby preventing any liability of the hook beingaccidentally melted ofi by the flame of the lamp. The shank of the hookis outwardly ofiset to form a shoulder which is located at theperforation, and which relieves the solid portion of strain. This manner of attachment makes the hook absolutely safe, and its durabilityover those soldered on the exterior of the body is vastly increased, asthe pointof'attachment is not exposed.

The bottom 6 of the rectangular lamp body is provided with a forwardextension 7, which forms a seat for the wick tube, and the lattercommunicates'with the lamp body through an opening in the front wallthereof; and it is brought more closely to a vertical position than ispossible where the wick tube is secured directly to the front of thelamp body, above the bottom thereof. a

The wick tube is extended considerably above the body of the lampwithout making the'lamp top heavy, owing to the closeness or nearproximity of the tube to the body; and the entire front and top of thebody is protected from the flame by a removable shield 8. The height ofthe wick tube and its particular arrangement, also serves to keep theflame of the lamp out of the face of the wearer, to prevent burning him,or singeing his hair or filling the eyes of the wearer with smoke. Theshield is substantially L-shaped in side elevation. It extends over thefront and top of the lamp body, and it is provided at its top with acircular opening 9, to receive the flange 1O surrounding the fillingopening of the lamp body. The front of the shield is bifurcated, and theopposite sides formed by the bifurcation straddle the wick tube 3 andterminate in flanges 11, which engage under the bottom of the lamp bodyat opposite sides of the extension 7,whereby the shield is detachablyand securely fastened to the lamp. The shield is separated from the topand front of the lamp body to provide an intervening air space,wherebyall liability of heating the lamp body to a dangerous degree isprevented.

The annular flange 10 consists of a short tapering tube, and receives ahinged dished cover 12 provided at one side with a flange or handle 13,and having at an opposite point an eye 14, arranged between oppositeeyes 15 of the tapering tube 10, and receiving a pintle 16, whereby theparts are hingedly connected without employing solder. The eyes of thetube 10 are disposed at a slight angle to that of the cover, and thepintle, which passes through all of the eyes, is slightly bent at each'end, thereby preventing any liability of its accidentally becomingdisplaced.

The cover consists of a circular portion and a surrounding upwardlyextending tapering flange 17, which fits within the tapering tube 10. Itis located below the upper edges of the tube; and it is adapted toreceive and convey back to the body of the lamp any overflow, aperforation 18 being provided for that purpose. The tapering tube andthe cover have a slight rearward inclinationthat is, the front of thetube 10 is higher than the rear edge-in order to bring the cover and thetop of the tube in an approximately horizontal position in use. Theinclined cover, and the perforations thereof, cause any oil accumulatingin the dish-shaped cover, through the jolting of the lamp or otherwise,to drip back into the lamp to avoid getting the oil on the clothesof thewearer.

In Figs. 4 and 5 of the accompanying drawings, is illustrated amodification of the invention, and a construction is shown especiallydesigned for burning petroleum or hydro-carbon oil, the previousconstruction heretofore described being designed for burning animal oil,or what is known as miners oil. The tube 19 shown in Figs. 4 and 5, iscylindrical. It communicates at the bottom by a narrow opening 20 withthe body of the lamp; and it contains a removable Wick tube 21, which isadapted to be withdrawn fromthe stationary tube 19 for adjusting orapplying a wick. The bottom of the wick tube is designed to' be providedwith a partial filling of fabric, which is closelypacked, and which isdesigned to check the flow of oil from the lamp body to the tube 19, inorder to permit only a saturation of the wick, and to prevent anyliability of such oil running out of the wick tube when the latter is ina more or less. inclined position.

The shield 23 is detachably secured to the lamp body and to the wicktube 19 by means of bands 24, each constructed of a single strip ofmetal having its ends passed through slits in the front of the shieldand bent laterally against the inner face of the shield, therebyeffecting a fastening of the bands without employing solder or the like.The top of the shield is provided with an opening to receive the tube ofthe filling opening.

The fiat rear face or back of the lamp body, is adapted to slide freelylaterally on a cap to cause the lamp to assume a perpendicular positionwhatever be the position of the wearer; and this construction obviatesthe necessity of employing particular forms of connections forpermitting such a swinging movement.

It will be seen that the construction is simple and inexpensive, that itpossesses great durability, and that it renders thelamp economical, asit prevents any waste of the oil.

It will also be apparent that the tapering tubeof the filling openinggreatly facilitates the insertion of cotton or other filling employed tocheck the flow of oil from the body or reservoir of the lamp to the wicktube. The body of the lamp is protected from the flame, thereby enablingthe lamp to be used in passages where there is a strong current of air.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

' What I claim is- 1. A miners lamp provided with an approximatelyL.-shaped shield, extending over the front and top of the body of thelamp, and forming an intermediate air space between it and the front andtop of the lamp, which space is open at the sides, said shield beingdetachable and interlocked with the lamp at the top and bottomthereof,substantially as described.

2. A miners lamp provided at its top with an annular flange, combinedwith an approximately L-shaped shield having at the top a circularopening to receive the annular flange, and provided at its front with abifurcation to receive the wick tube, and having at its lower edges atopposite sides of the wick tube, flanges engagingunderthebottomofthelamp, substantially as described.

3. A miners lamp having a filling opening and provided with a taperingtube secured at its lower end within the opening, combined with adishshaped cover hinged at one side to the tube and having the upperedge of its flange located within the tube below the upper edgesthereof, substantially as described.

fl. In a ininers lamp, the combination of a lamp body provided at thetop with an opening,'an inclined tapering tube secured in the opening ofthelamp body and extending above the top of the same and having itsfront edge higher than the rear edge, and the tapering dish-shaped coverarranged at an inclination in the tube and hinged to one side thereof,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

- WILLIAM G. PRICE.
